VASTU SHASTRA GUIDELINES | OVERHEAD / UNDERGROUND TANK

VASTU SHASTRA GUIDELINES | OVERHEAD / UNDERGROUND TANK

There are two Water Tanks that are required in a House:

The Underground Water tank also known as the Sump. The municipal water pipe is connected to the Sump. Hence this tank has to be close to the road as the water lines run along the road. Usually it is located below the Car Porch/Garage.

The Overhead Water Tank. The water from the sump or Well/Borewell has to be pumped into the Overhead tank in order for it to be able to flow down into the house.

Here, I have explained the Vastu Guidelines for Water Tanks. Since Vastu is a science, there is logic and reasoning behind every guideline. As an Architect, I have attempted toexplain these guidelines rationally and scientifically, so that you can decide what you want to follow and what you don’t.


SUMP / UNDERGROUND WATER TANK

WHAT IS THE BEST POSITION FOR A SUMP OR UNDERGROUND WATER TAN, ACCORDING TO VASTU?

The Sump should be located in the North-East corner : The Logic -Since Vastu recommends that the North-East corner of a site be left open, to allow the useful morning sunrays to enter the House,  it makes sense to have both the Water source as well as the Sump close to each other in this corner (since they are anyway under the ground and will not obstruct the light). However, if the sump is used for storing the municipal water, it makes  sense to have it in the  front, as you will need a shorter connection to the municipal water lines.
The Sump should not touch the compound walls or the building walls: The Logic -The sump should be a separate structure and should be kept a little away from the compound and building walls, to prevent any kind of dampness from seeping up the  walls.

OVERHEAD WATER TANK

WHAT IS THE BEST POSITION FOR AN OVERHEAD WATER TANK ACCORDING TO VASTU?

The Overhead water tank should be in the West or South-West of the building: The Reasoning - The South-West corner should be the heaviest, to create a balance of positive energies in the house/building.

Avoid the Overhead tank in the North-East corner of the House: The Reasoning – Though the North-East corner represents Water, avoid a tank here because the North-East has to be the lightest part of the house for a balance of positive energies.

Avoid the Overhead water tank in the South-East corner. Also, avoid the Overhead water tank in the North-West corner (if possible). However if it can be located only in the North-West, then it should be small in size, of less height, and situated at a distance of at least two feet from the North-West corner. The Scientific Reason – The basic rule in Vastu is that the building should be higher in the South and West sides and should be much lower in the North and East sides. By keeping the North and East sides much lower, constant sunlight from the North and morning sunlight from the East can reach all parts of the house, whereas  by raising the building on the South and West sides, the hot evening sun will be prevented from heating up the rest of the house.

Avoid the Overhead tank in the centre of the building (Bramhasthan) -  as  it is a load on Bramha, the supreme one. The Scientific Reason –  Structurally it is not safe to have a water tank in the middle of the house roof, unless it is a column-beam structure.

The overhead tank should not directly rest on the roof slab

WHAT ARE THE VASTU GUIDELINES FOR THE DESIGN OF AN OVERHEAD WATER TANK?

The Overhead tank should not directly rest on the roof slab: The Scientific Reason – In case there is a leak in the tank, the dampness can seep into the building causing structural damage and fungus growth which is not good for the health of the family.

The Overhead tank should be at least 2′ (60cm) above the topmost roof slab: The Reason -The higher the water tank is above the building, the greater will be the pressure of water, thus enabling the water to flow in full force in all the taps.

The Overhead water tank can be lined with light coloured tiles: The Logic – This will ensure cleanliness of the tank, as it is easy to maintain and there is less likelihood of growth of fungus. Moreover, the white tiles allow one to see all the dirt while cleaning.

Avoid plastic water tanks as far as possible: The Scientific Reason – We are still not sure about the health hazards of storing water in plastic containers. But today because of the convenience of plastic tanks and the inevitable leakage of concrete tanks, we are seeing more and more plastic water tanks.

SINTEX-WATER-TANK

Plastic water tanks are available in different sizes and capacities

In case you use plastic water tanks, use black or dark blue coloured ones:The Scientific Reason – Dark colours prevent the sun’s rays from entering the tank unlike light-coloured or transparent tanks. The sunlight that enters will encourage algal growth. (Thanks to Manoj for the correction).

Two separate Overhead water tanks are preferred – One , for storing water for drinking, cooking etc and the other, for storing water for bathrooms, gardens etc: The Logic – Nowadays, due to the shortage of piped water, it is advisable to use this water only for cooking and drinking purposes, as it is generally chlorinated, purified water. The water from an additional water source, like Well or Borewell within the site can be used for Bathrooms and Toilets as you may not be sure of the purity. Naturally the water from theses two sources should not mix and so it is better to have two separate tanks.

The Solar geyser should be above the level of the overhead water tank: to ensure proper flow of water, and all the equipment attached to the same should be installed in the South-East of the roof. The Scientific Reason – Since the South East is considered the corner representing Fire, ‘Vastu pundits’ generally recommend that all electrical and heat related appliances be placed in the South-East. That is the only scientific explanation!

The Overhead tanks are located on top of the roof and are accessed by the Staircase. Read the Vastu Guidelines for a Staircase here:

  3. bharath says:

    my house is an west facing portico and the main door is in north west ,i have a small sump in noth east corner , due to water shortage i wanted to construct a sump in northwest corner which is a portico also ,. should i do that for me it is important, what are the effects from the sump being in north west .plse let me know.

    Dear Mr Bharath,
    The best thing to do would be to enlarge the existing sump in the north-east, either in area or in depth, since the municipal water connection must be already in this corner. But if there is a space restriction, then it makes sense to have another sump in the North-West corner, since it is also an open portico. But make sure this doesn’t mean extra expense for another pump and for the change of the municipal connection.

  4. Dr Mukaesh Agrawal says:

    Please write on detail about underground water tank below Car porch/Garage in North-west Corner. because u r write somewhere that underground watertank present only in north-east but some where below car porch.
    Hi Dr Agrawal,
    I have quoted what Vastu Shastra recommends – the “ideal position” for a sump is the North-east. But this does not mean that it is the only acceptable position. You have to look at different factors such as: the corner that has ample space for a big sump, the corner that is closest to the municipal water lines, easy accessibility to the sump and ample space around the sump for maintenance and cleaning. Most people put their sumps below the car porch or garage, because most of the above mentioned factors are met.

    Hi Sridhar,
    If the existing sump is small and you want a bigger one in the South-West, go ahead. Just make sure the municipality water lines can be easily connected to this position.

  7. Dr Agrawal says:

    CORRECTION.

    One comment says dark tanks are good because they absorb sun’s UV rays which purify water. WRONG. The UV rays can only purify water if the tank is clear and the UV rays can enter inside to kill bacteria. Please remove that comment, it is misleading.
    Hi Dr Agrawal,
    You are right – dark coloured tanks will reduce the absorption of UV rays. Thank you for the correction. And as Mr Manoj has rightly said, “the dark coloured tanks limit the passage of sunlight to water. White or transparent tank would readily allow most light to pass to water in the tank. Sun Light will promote algae growth on the surface of tank.” I have made the correction.

  8. Manoj says:

    Correction. Dr.Agrawal. I understand that dark coloured tanks will limit the passage of sunlight to water. White or transparent tank would readily allow most light to pass to water in the tank. Sun Light will promote algae growth on the surface of tank. This is the reason. No funda of UV etc.

  10. Mihir says:

    Can I construct the compound Gate over the underground water tank ? Is it permitted by vastu shashtra ?
    Although the opening of the tank would not come in front of the gate, but the gate lies above the underground tank.
    Hi Mihir,
    How can the underground tank project beyond the compound wall line. I assume the gate is above the end of the underground tank in which case it is okay.

  11. Suresh Rai says:

    Presently I have a Water Tank 2 feet underground and 3 feet above ground level at the South East corner of the verandah. I want to remove it from there and make the ground level in the South East corner, and install an underground water tank in the South West corner of the verandah. I know that installing the overhead tank in the South West corner is the best solution as suggested by Vastu, but it is the frontage of the house and an overhead tank would spoil the frontage design and would also block the light and air to the drawing room. I can also consider the underground tank in the South West corner which is 4 feet underground and one feet above ground. Can you suggest the best solution given the constraints. Thanks in advance.
    Hi Suresh Rai,
    Since your house faces South, It is better to have your underground tank in the South either in the SE or the SW corners. But have it completely below ground. The over head water tank can be towards the back of the house as you rightly say that it spoils the front elevation. Do not compromise just because Vastu Shastra recommends certain”ideal” positions.

    I am having south facing house……..can make water sump under stair case in south west area of the house.
    Pls advice.
    Hi Deep,
    If there is no space in front of your house, then only think of putting the sump under the staircase. Make sure the staircase structure is safe and the sump cover is open able outside the house for maintenance.

  13. Naveen says:

    My house plot is constructed on the mountain rock which lies at the east side of the plot. The under ground water tank is constructed in north west corner due to the reason that its hard to demolish the rock at north east. Is this OK ?
    Hi Naveen,
    Being practical is being sensible. There is no point in wasting money on demolishing a rock just so that the sump can be constructed in the “ideal” vastu position, the North-East. Vastu advocates being practical.

    Hi,As I am having a southwest facing house,I have an open space in southwest.The directions N,E,S,W are at the corners of my house.Now I want to construct an underground water tank.Plz suggest me the right positrion for it .As I live at Dehradun,a semy hill station,the slop of my house is towards southwest.I also want to know that can I cunstruct an underground tank under one of my rooms(without touching the walls) that is in the north of my house? I don’t have an open space in North east direction.Plz give me your suggestions as soon as possible because some renovations are due in my house and i want to start the work as soon as possible.
    Hi Indu Sharma,
    Since your house is South-West facing, you have open space in the South west and your site slopes towards the South west it is better to have the sump in this location. Do not put the sump under the house as it will be difficult to maintain and any leak and overflow may go undetected and affect the foundation of your structure.

    my house is east facing. There are two bedroom & hall & kitchen according to vastu.There is also one room on south east corner on second floor. my overhead tank sevenfeet position at south west corner of plot. which is not equal to the roof of south east corner. because there is a room at south east.(aagney cone). please suggest me am i right.
    Hi Vandana,
    I have not understood your query. I assume that you are concerned that the roof level of the SE room is more that the level of the water tank in the SW corner. This difference in roof heights will matter only if, there is a water connection to the SE room because water flow may be limited.

    my house is south facing but entry door is west facing i have to construct a sump below the staircase at east south side of the plot because there no other space. what should i do ?
    Hi T Baban,
    Go ahead and build it in the South-East. It will be close to the municipality water lines.

    I have an independant house north facing. I plan to build a sump now but in the north east there are pillars columns hence please suggest the alternate position , this is urgently required as there is no water in chennai. Thank you so much in advance.
    Hi Venkat,
    Since yours is a North facing site with municipal water lines in this direction, it is practical to have your sump anywhere in the North side of your plot . If the space available is narrow, make a deep sump. But do not try to fit it in between structural columns

    My house is East facing and the entry/Main door is also East facing.An underground water tank is in the north-west comer(Vayavya-khuno).Just I want to know for myself, that is it harmful in future? One Vastrushashtri informed me that this underground tank will begin to give result after seven years. We purchased this house before 4 years.
    Nirmala
    Hi Nirmala,
    Why will it take 7 years for the bad effects? Of course, in those 7 years if you do not maintain the sump regularly there can be bad effects on your health.

  19. T.Sen says:

    My house is south facing but area is very short, due to that I have no place to build the sump out side of my house. My Kitchen is on north-east side and one old short defective sump was under the kitchen, municipality water line entered from South to my under ground sump, If I renovate that sump and make it under Kitchen, then what I should to do is there any problem for our future. Please reply immediately because I have to build within a week.
    Hi T Sen,
    A sump under the house is not a good idea. Sometimes the sump may overflow, maintenance of such a sump is very difficult. Ideally you should use your setback area for a sump- even if it is narrow, you can increase its capacity by making it deep. I do not think renovating your sump without affecting the house structure is possible.

    We are constructing house and almost 65% of work is done. We have borewell in north east portion of the site and as there was shortage of space we made sump in north west side. I want to know if I can leave it as it is or should I think of some solution.

    Hi Roopa,
    I personally think there is nothing wrong with your sump and borewell positions. You just need to make sure that the sump is leak proof and large enough to store water for your daily use, so that it gets circulated and does not remain stagnant.

    Hello sir..
    there is water leakage problem in my house but we could not found where it is actually.. My family members suffering from health problem..i think this is done by water leakage..so please give me solution…water tank is placed in north west direction on the second floor and it is white color painted…
    Hi Girish,
    It is nor clear where the water is leaking. I suggest you get a good plumber to check all your pipes and water tank and set right the problem. You are right in thinking that the persistent water leakage(dampness) must be affecting the well-being of the inmates. So get the problem rectified at the earliest.

    northeast of my house is higher than all other corners.
    my house being at corner of south & west my north side is higher.
    overhead tank is at center to the east wall.
    please find me solution….
    Hi Rohit Kumar,
    In vastu,it is recommended that the North-east portions be lower than the south-west so that the morning sun rays that enter the house from the North-east, can permeate the whole building. Since your site is higher in the north-east, lower the compound wall and have a lot of open space in this direction, so that sunlight is not blocked.

    Is overhead tank to south is OK?
    Our house staircase is to South and we are using the staircase headroom for Overhead tank. Is this OK?
    Hi Anita,
    The overhead tank in the south can reduce the effect of the hot afternoon sun rays that come in from the South.

    Hi Sharad,
    I think you are unnecessarily linking the newly constructed water tank with your problems. Focus on your work and look into yourself because anyway, you cannot control what the owner does to his building. Good luck!

    I have an twin house single floor north facing separated with common wall in between. I have the sump in north west corner of
    one portion & stair case in north east of other portion is it ok according to vastu or need to interchange, i am planning to construct the 1st & 2nd floor if really important will do it because front passage is about 6/50 (sump of 5/10 almost)
    common separated with small 4 feet wall in middle of two house
    this is urgently required. Thank you so much in advance.
    Hi Balasubramanya K,
    Since you are planning to construct further and are willing to make changes, go ahead and interchange the staircase and the sump as it will free up space in the North-East corner. Make sure you have lots of windows in the NE corner.

    Sir,
    as per vastu construction of underground sump in southwest is acceptable or not. pls suggest its side effects and correction if constructed in southwest as there is no other space .
    regards
    manjunath
    Hi Manjunath,
    There is no hard and fast rule about the position of the sump (underground water tank). Practically speaking, it should be closer to the road since connection to the municipality water lines becomes easier. So, If your site is a south facing one, then the sump will be towards the South. Don’t worry about it.
